Title (EN) METHODS AND SYSTEMS FOR ASSISTING OR REPAIRING PROSTHETIC CARDIAC VALVES
(FR) PROCÉDÉS ET SYSTÈMES POUR RENFORCER OU RÉPARER DES VALVULES CARDIAQUES PROTHÉTIQUES
Abstract:
(EN) A prosthetic valve coaptation assist device includes an anchor and a single valve assist leaflet. The anchor may be a supporting ring frame, brace or arc structure and will usually be radially self-expandable so that it can expand against surrounding natural or prosthetic tissue. The valve assist leaflet may be made of pericardium or other biological or artificial material and is shaped like the native target valve leaflet. The valve assist leaflet is typically sized larger than the target natural or prosthetic leaflet so that after implantation a significant overlap of the device body occurs.
(FR) La présente invention concerne un dispositif d'aide à la coaptation d'une prothèse valvulaire, ledit dispositif comprenant une ancre et un feuillet d'assistance valvulaire unique. L'ancre peut être un cadre annulaire de support, une entretoise ou une structure arquée et sera généralement radialement auto-expansible pour pouvoir se déployer contre un tissu environnant naturel ou prothétique. Le feuillet de renforcement valvulaire peut être constitué de péricarde ou d'un autre matériau biologique ou artificiel et a la même forme que le feuillet valvulaire natif cible. Le feuillet de renforcement valvulaire a typiquement une plus grande taille que le feuillet cible naturel ou prothétique de manière à permettre, après l'implantation, un chevauchement significatif du corps de dispositif.
